WINDMILL-DERRICK.

SPECIFICATION forming part of Letters Patent No. 375,378, dated December 27, 1857.

Application filed September 13, 1886. Serial No. 213,368. (No model.)

To all whom it mag concern.-

Be it known that I, THOMAS O. PERRY, a

. citizen of the United States, residing at Te cumseh, in the county of Lenawee and State of Michigan, have inventeda new and useful Windmill-Derrick, of which the following is a specification.

The objects of my invention are, first, to provide a support for sustaining a windmill high in air while in use, and which shall admit of readily lowering the windmill to the ground or where it can be easily reached, so as to do away with the necessity of climbing whenever it may be desirable to oil the bear-' ings or make repairs, or so as to avoid damage in case of storm, and, second, to facilitate the erection of the wind-mill and reduce cost. 'I'

attain these objects by the mechanism illus trated in the accompanying drawings, in which 7 Figure 1 shows the derrick supporting a windmill high in air ready for use; and Fig. 2 illustrates the method of lowering the windmill to the ground for oiling, Ste. Fig. 3 is a sectional detail ofthe coupling G on the rod R.

Similar letters refer to similarparts in all cases. I

K L represent the surface of the ground, from which rises a fixed post or support, B, held firmly by any suitable means in an upright position. The post B supports a mast, A, on a horizontal pivot, O, at or near the top of the post. To the top of the mast A is secured a windmill in the ordinary way, and at the foot of the mast a weight, I), is attached, so that the mast, with windmill and weight, may balance, or nearly so, on the pivot 0. At the foot of "the mast is also attached an ear, E, which is bolted or in some way fastened to the post B, so as to secure the mast in an upright position when the windmill is in use. The mast may be further steadied, if necessary, by guys P Q, attached to the mast at J and secured at their lower ends to any convenient fixed objects. The fastening at E maybe dispensed with if guys are used to hold the mast upright.

The wind mill is supposed to impart, by means of a shaft or rod, R R, either rotary or reciprocating motion to machinery of some kind on the ground or somewhere beneath the pivot O, and the shaft or rod RE is provided with a flexible joint or hinge, H, opposite or near to the pivot O. In case of arevolving shaft there should be a universal joint in line with the axis of pivot O. In the drawings the. Windmill is represented as attached to a common pump, F, and if the reciprocating rod R below pivot C be sufficiently flexible no trouble will arise from a small displacement of thejoint H. Otherwise the rod B may have another joint at G near the foot of mast A. The rod R is provided with guides S, one of which should be attached to the mast near the joint H. R R also might representapipe for conveying compressed air down from an aircompressor worked by the windmill above, in which easethe guide S would represent astaple for holding the pipe in place.

In order to lower the windmill for oiling, 820., it is only necessary to take off the nut or loosen the fastening which secures the foot of mast A to post B and turn the mast on its pivot until the windmill is brought to the ground or within reach; and of course thereverse of this process raises the windmill again to its working position. When guys P Q are used, the guy Q should be unhitched at its lower end before attempting to swing the mast from its vertical position, and the flexible guy P can conveniently-be used as a means for pulling the windmill down. of its own accord return to the vertical position if the weight D be so heavy as to somewhat overbalanoe the windmill. The addition of the weight D to the foot of the mast may not always be necessary, as the weight of the mast itself may be so distributed with reference to the pivot Gthat it, with windmill attached at top, will properly balance; neither is the joint H in the rod R R indispensable, as the rod or shaft It may be simply disconnected at G near the ground whenever it is re quired to turn the mast on its pivot, and both parts of the rod or shaft R B may be supported in guides or bearings fixed at suitable intervals along the mast A. In this case the rod or shaft B, when connected at G, might serve as sufficient fastening to hold the mast in upright position.

A mast pivoted and balanced as herein shown and described would be useful for sup porting not only windmills, but other apparatus which requires occasional atteutiomsuch as electric lamps, signals, 85c.

What I claim, and desire to secure by Letters Patent, is-

1. In combination with a windmill actuating a rod or shaft for communicating motion, a sustaining-mast pivoted to a fixed support and balanced so that on being released it may be readily turned about its pivot from its normal upright position to bring the windmill to the ground or within easy reach for oiling and such attentions as may be occasionally required, substantially as herein shown and described.

2. In combination witha windmill sustained by a mast pivoted to a fixed support, a shaft or rod having asuitable joint or hinge at or near the axis of the pivot about which the mast is turned, so that the windmill, without nncoupling or disturbing the shaft or rod, may be lowered to within easy reach for oiling and such attentions as may be occasionally required, substantially as herein set forth.

3. In combination with a windmill sustained bya mast pivoted to a fixed support, a rod or shaft for communicating motion, having at or near the foot of the mast a release joint or coupling,whereat the rod or shaft may be disconnected, so as to allow'the mast to swing on its pivot as required for lowering the windmill, substantially as set forth.

4. In combination with a windmill sustained by a mast pivoted to a fixed support, a rod or shaft for communicating motion, held by guides or bearings attached to the mast, and having at or near the foot of the mast a releasejoint or coupling,whereat the rod or shaft may be disconnected, so as to allow the mast to swing on its pivot as required for lowering the windmill, substantially as and for the purpose herein set forth.

5. In combination with a mast pivoted to a fixed support and sustaining at its upper end a windmill or other apparatus requiring in normal use a fixed elevation, means for securing a mast in its normal upright position by means of fastening which admits of ready re leasing whenever it may be desired to swing the mast on its pivot in order to lower the windmill or apparatus, substantially as and for the purpose herein specified.

6. The combination embracing the windmill or apparatus W, mast A, pivot O, support B, and detachable fastening E, substantially as and for the purpose herein shown and described.

7. The combination embracing the wind mill or apparatus W, mast A, pivot C, support B, and guys I Q, substantially as and for the purpose herein set forth.

8. The combination embracing the windmill W, mast A, pivot 0, support B, guides or bearings S, and rod or shaft R R, having detachable joint or coupling G, substantially as and for the purpose herein set forth.

9. The combination embracing the windmill W, mast A, pivot 0, support B, detachable fastening E, guide S, and rod or shaft It R, having hinge or joint H, substantially as and for the purpose herein specified.

10. The combination embracing the windmill \V, mast A, pivot 0, support B, guys P Q, guide S,and rod or shaft RR, having hinge orjoint H, substantially as and for the purpose herein specified.

11. The combination embracing the windmill \V, mast A, pivot 0, support B, detachable fastening E, guys I? Q, guides or bearings S, and rod or shaft R R, substantially as and for the purpose herein set forth.

12. The combination embracing the windmill VV, mast A, weight D, pivot 0, support B, detachable fastening E, guide or hearing S, and rod or shaft R It, substantially as and for the purpose herein set forth.
